CDCP1, also known as SIMA135, is a novel 140 kDa type I transmembrane glycoprotein with three CUB protein-protein interaction domains in its 635 aa extracellular region. The 148 aa cytoplasmic region contains canonical phosphorylation sites for Src kinase family members and binding sites for SH3 domains. By alternative splicing, a secreted 310 aa residue form of CDCP1 also exists. The amino-terminal region of approximately 265 aa of the type I membrane CDCP1 can also be proteolytically cleaved. CDCP1 is found on the surface of epithelial and bone marrow-derived stem cells. The extracellular region of human CDCP1 shares 84% aa identity with that of the mouse protein.

Detection of CDCP1 by Western Blot
Co-overexpression of Src and CDCP1 leads to focus formation.(A) Fifty thousand NIH3T3 cells were infected with 500.000 retroviruses encoding CDCP1 or Src individually or together. After 48 h the cells were reseeded in a 10 cm-dish and grown for 3 weeks, with 3 media changes per week. In parallel, a 2% aliquot was taken from the CDCP1/Src infected cells and reseeded together with 150.000 parental NIH3T3 cells (1∶50 dilution). Finally, the cells were stained with crystal violett. (B) Parental NIH3T3 cells, cells infected with the CDCP1 encoding retrovirus or individual foci derived from infections at lower m.o.i. than in A that had been isolated and expanded, were lysed, aliquots with similar amounts of protein run on an SDS-PAGE, proteins transferred to nitrocellulose and the filter blotted with the indicated antibodies. alpha PY, anti-phosphotyrosine. Size markers (kDa) are indicated. Image collected and cropped by CiteAb from the following open publication (https://pubmed.ncbi.nlm.nih.gov/23300860), licensed under a CC-BY license.
